This article briefly explores the reasons why the Committee of the Regions (CoR) has only partially accomplished its representative function. It is divided into three parts. In the first part I argue that the ambiguous nature of the CoR is the consequence of the polysemous notion of âregionâ in EU law (Palermo, 2005) and of the very heterogeneous approach to the âfederal issueâ in Europe. In the second part of the article I look at the recent developments that have given the CoR new powers, for instance in light of Art. 263 TFEU in order to defend its own prerogatives and Art. 8 of Protocol No 2 on the application of the principles of subsidiarity and proportionality. This will be done by looking at a recent resolution of the CoR on a proposal made by the EU Commission to amend Regulation (EU) No 1303/2013. Finally, I deal with some proposals that have been advanced to strengthen the role of the CoR, and their feasibility.
